BEARING FOR REVOLVING SHA FTS.

Specification of Letters Patent;

Application filed April 11, 1905. Serial No. 254,923-

To all whom it may concern.-

Be it known that I, PAUL Sonou, civil engineer, a citizen of Denmark,residing at C0- penhagen, Denmark, have invented new and usefulImprovements in Bearings for Revolving Shafts, of which the following isa specification.

The object of this invention is to provide an elastic bearing for arevolving shaft.

The elastic eflect of the bearing is obtained by inserting a ring filledwith fluid between the bearing itself and the part of machinerysurrounding same. The principal feature of the invention is that thewhole surface of the said fluid-ring is arranged to bear against thewalls of the said parts even if these move in relation to one another.Consequently the elastic walls of the fluid-ring itself will never atany point be freely exposed and may therefore be made quite thin.

The invention is illustrated on the accompanying drawings, whichshow.various constructional forms of the bearing.

Figures 1 and 2 are vertical sections illustrating various bearings ofthe said construction. Fig. 3 is a detail plan view, partly in section,of one form of safety-ring; and Fig. 4, an elevation of one-half of thering.

In the construction shown in Fig. 1 a protecting-ring 7c is providedwith two annular flanges embracing a flexible fluid-ring b, preferab y,though not necessarily, made of india-rubber, so that its outer, upper,and lower surfaces bear against the ring 7c, while its inner surfacebears against a bearing a for the shaft. (Not shown.) Flanges g, formedon the ring lc, are made to fit into corresponding grooves of thebearing a, and between the flanges and the bottom of these grooves areplaced rings 1', of india-rubber or other elastic material. By thisarrangement the rmg'k will act as a safety-ring if the fluid-ring I;should burst and the fluid run out while the shaft is turning at fullspeed. If this should happen, the ring 7c, together with the flanges andthe elastic rings 1", will temporarily steady the shaft untilcircumstances permit of the fluid-ring being replaced. 4

The support for bearing a is here shown as 5 comprising two rings m andn, fastened to a ring f, and the whole support is fixed to the frame ofthe machine by means of bolts g.

The ring is (shown in detail in Figs. 3 and 4) consists of twosemicircular parts each rovided with an annular strengthening-ri s, thetwo parts being connected by means of screws t. The rings on and 'n areso shaped as to form a recess o, that allows the rib s to move freelywhen the ring is is assuming an inclined position. One of the screws thas a rather high head, Fig. 3, which by projecting into a cut-away partof the rings m and it serves to revent the ring 1c from rotating withthe sl faft.

In Fig. 2 is shown a safety-ring k in which it is not necessary to cutthe ring radially. A bearing a is in this case provided at the lower endwith a fixed flange u and at its upper end with a screw-thread forreceiving a loose flange w. When the flange w is unscrewed, the ring iscan be slipped in its place until its lower fixed flange rests againstthe flange u of the bearing. in upper flange g of the ring is is made tounscrew, and on the cylindrical part of the bearing a is slipped a ring1), which is cut away at top and bottom, so as to form, in connectionwith the flanges u and 'w, grooves for the flanges g and g In the formsof construction described the bearings a and a are rovided with suitablechannels for leading ubricant to the inner surface of the bearing.Suitable means, such as pins 1), are provided for preventing the bearinga, from rotating with the shaft.

I claim- 1. In a bearing, the combination with'a support, of a bearinghaving grooves formed therein, a protecting member mounted on thesupport and having flanges projecting into the grooves of the bearing,and a flexible fluid-filled ring mounted between the flanges.

2. In a bearing, the combination'with a fixed support, of a bearinghaving grooves formed in its periphery, a ring mounted on the supportand having flanges taking into the grooves, and a flexible fluid-filledring mounted between said flanges and in contact with thefirst-mentioned ring and bearing.

3. In a bearing, the combination with a fixed support having a recessformed therein,

Patented Au '7'; 1506? of a two-piece protecting member having a rib onone face protruding into said recess and parallel flanges on itsopposite face, a bearing having grooves formed therein to receive said 5flanges, a flexible fluid-filled ring mounted between said flanges incontact with the protecting member and bearing, and means to preventrotation of the protecting member.
